The High Court is to rule on whether the Crown Prosecution Service's decision not to charge any police officers over the killing of Jean Charles de Menezes "violates" his family's human rights.

Mr de Menezes, a Brazilian national, was shot dead on July 22 last year after police mistook him for a suicide bomber at Stockwell tube station in south London.

Family lawyers argued at a recent two-day hearing that if no individual officer was personally held accountable for the death of the 27-year-old electrician "the rule of law would be undermined".
